He is an interesting literary figure. And in personal opinion quite frankly kind of a hack. You got to appreciate the audacity of someone who tries to use “Dost” nearly two centuries out of date and then just out of the blue makes up wholesale complete words from scratch to fit iambic pentameter.

I love his stuff don’t get me wrong but he wasn’t exactly highbrow entertainment of his day. Still his early modern English is easily legible. Chaucer’s middle english is distinctly more garbled and if you go back to your Old English where these terms originate it’s like trying to read another language entirely. Like this is technically English :

Hwæt. We Gardena in geardagum, þeodcyninga, þrym gefrunon, hu ða æþelingas ellen fremedon. Oft Scyld Scefing sceaþena þreatum, monegum mægþum, meodosetla ofteah, egsode eorlas. Syððan ærest wearð feasceaft funden, he þæs frofre gebad, weox under wolcnum, weorðmyndum þah, oðþæt him æghwylc þara ymbsittendra ofer hronrade hyran scolde, gomban gyldan. þæt wæs god cyning.
